Spacebar Magnifies Photos in iPhoto '08

In iPhoto '08, you can choose whether double-clicking on a photo will edit it or magnify it. I prefer my double-clicks to edit photos, but every now and then it's nice to magnify a photo. To do that, even when double-click is set to edit, just select the photo and press the Spacebar.
